STATION-INDICATOR LPEGIFICATION forming part of Letters Patent No.285,158, dated September 18, 1883.

Application filed January 9, 1883. (X0 model.)

To all whom it may concern: 7,

Be it known that I, ISAAC NE TON'PHIL- LIPs, of Nashville, in the countyof Davidson and State of Tennessee, have invented certain new and usefulImprovements in Station-Indicators, of which the following is a full,clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar'letters of reference indicatecorresponding parts in all the figures.

Figure 1 is aside elevation of my improvement, parts being broken away.Fig. 2 is a side elevation of the lever and pawls, and showing parts ofthe inner ratchet-wheel and the slide. Fig. 3 is a front elevation ofthe same, parts being broken away.

The object of this invention is to promote convenience and certainty inmaking known to passengers the name of the next station.

A represents a case, which is designed to be secured to the end of a caror other suitable support and in bearings, in the sides of which revolvethe journals of a drum, B. Upon the front of the case A, near its ends,are printed the names of the stations at the termini of the line. Uponthe face of the'drum B, and in their regular order, or upon strips ofpaper or other suitable material attached to the said face of the drum,are printed the names of the various stations of the road, and at theend of the name of each station, and directly under the names of thetermini of the road, are printed the distances of the said station fromthe said tern1ini,as illustrated in Fig. 3, the names of the stationsbeing seen successively through an opening inthe front of the case A.One of the journals of the drum B projects, and to it, at alittledistance apart, are attached two rat-chet-wheels, C D, arranged withtheir teeth pointing in opposite directions.

To the journal of the drum B, between the two ratchet-wheels O D, ispivoted the angle of a: right-angled lever,E,the end of the upper arm ofwhich is attached to a cord, F. The lower end of the cord F hangs insuch aposition' that it can be readily reached and operated by anattendant, and its upper end is attached to the trip-lever G of the bellH, which is-attached to the upper part of the side of the case A.

I is a rod which passes through and works in a hole in the upper arm ofthe lever B, and to its end parts are attached two pawls, J K, in suchpositions as to engage with the teeth of the ratchet-wheels O D. projectin opposite directions, as shown in Figs. 1 and 2, so that one of thesaid pawls will be held away from its ratchet-wheel when the other pawlis in working position. Upon the outer end of the red I is formed asmall crank, L, which projects at right angles with the pawls J K, andto it is attached the end of a spiral or other suitable spring, M. Theother end of the spring M is attached to the lever E. XVith thisconstruction either pawl The pawls J K J K can be brought into workingposition by adjusting the crank L, and will be held in that position bythe spring M until the crank L is adj usted into the other position. Theend of the lower arm of the lever E has two slots formed in it at rightangles with each other, to receive a slide-bar, N, and a pin attached tothe said slide-bar. The middle part of the bar N is curved downward, asshown in Figs. 1 and 2, to bring it into proper position to engage withthe lever E. The end parts of the barN are straight and slide throughbearings O, attached to the case A.

To the end of the drum B are attached pins P, arranged in a circle toengage with the ends of the slide-bar N, and thus stop the revolutionsof the said drum. \Vith this construction, when the pawls J K arearranged as shown in Fig. 1, a downward pull upon the lever E or cord Fwill draw the upper arm of the lever E downward and cause the pawl J torevolve the drum B. The same movement of the upper arm of the lever Ecauses the lower arm of the said lever to slide the bar N back, causingits rear end to project so that it will be struck by the next pin P andstop the revolution of the drum B at the proper point todisplay the nameof the next station. At the end of the line the crank L is adjusted tobring the pawl K into position to engage with the ratchet-wheel D, sothat the upward movement of the cord F, as it is drawn upward by thereturn movement of the trip-lever G, will revolve the drum Bin theopposite direction and display the stationnames in the reverse order. Ateach downward movement ICC of the cord F the bell H is struck to callthe attention of the passengers to the change in the indicator. The easeof movement of the drum B is regulated by the brake-springs Q, attachedto the ends of cross-bars Q, and which rest upon the face of the saiddrum at its ends, and are held down with any desired force by theset-screw R, as shown in Fig. 1.

The operating mechanism at the side of the case A is covered andprotected by a casing, S, which is secured to the side of the said caseA,and'is slotted for the passage of the lever E and crank. L.

Ha ving thus fully described my. invention, I claim as new and desire tosecure by Let ters Patent 1. A station-indicator constructedsubstantially as herein shown and described, and consisting of the drumprovided with two ratchetwheels operated by pawls connected with a lever, and stopped by a slide-bar engaging with pins attached to the saiddrum, as set forth.

2. The combination, with the drum-shaft and ratchets thereon, of theangled lever E, the cord F, the bell-trip lever G, the rod I, carryingthe pawls J K, the adjustable crank L, and the spring M, whereby thedown and up movement of the cord will respectively cause the drum tomove in opposite directions, as described.

3. The combination, with the drum B, having a circle of pins, andratchets O D on its shaft, of the lever E, having two slots at rightangles to each other, the cord F, and the slidebar N, carrying'a pin,said slide-bar being curved in the middle, straight at both ends, andarranged in bearings 0, whereby the drum will be revolved and the slideoperated simultaneously, as described.
